Morphoanatomy of <i>Schultesia pachyphylla</i> (Gentianaceae): a discordant pattern in the genus
Bibliographic record
Abstract
Schultesia Mart. comprises 21 closely related taxa. The revision of the genus showed that Schultesia pachyphylla Griseb. and Xestaea lisianthoides Griseb. are different from other species. The aim of this study was to describe the morphoanatomy of S. pachyphylla, comparing it with other Schultesia species and X. lisianthoides, and to provide data on their geographical distribution and habitat. Morphological and anatomical data were subjected to multivariate analysis. Schultesia pachyphylla is endemic to the state of Bahia, Brazil, and is separated from the other species by having 5-merous flowers, 5-winged calyx, wings between the calyx lobes, loss of interveinal tissue on sepals during fruit maturation, dark red colored immature calyces, capsules opening from base to apex, 3-anaporate pollen grains, and epidermal papillae evident in the field. Schultesia pachyphylla has amphistomatic leaves with anisocytic stomata, uniseriate epidermis, dorsiventral mesophyll, and bicollateral vascular bundles. The stem has small wings, cortical and medullary parenchyma, and internal phloem. Foliar colleters and nectaries on leaves and stem were observed. We believe that morphological and anatomical data could support the creation of a monotypic genus or the relocation of this species into another genus. Phylogenetic analyses are in progress to define the species’ positioning.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
